Specification of Letters Patent.

Patented July 7, 1908.

Application filed January 21, 1907. Serial No. 353,259.

To all whom it may concern:

Be it known that we, HERBERT B. GIL- LETTE and CHARLES W. DAKE, citizens of the United States, residing at the city of Grand Rapids, county of Kent, State of Michigan, have invented certain new and useful Improvements in Roller-Bearings, of which the following is a specification.

This invention relates to improvements in roller bearings.

It relates particularly to roller bearings having conical rollers and cones.

The objects of this invention are, first, to provide an improved roller bearing having conical rollers and cones in which the bearing rollers are retained without the use of cages or journal pins therefor. Second, to provide an improved roller bearing having conical bearing rollers and cones in Which the rollers impinge each other and both cones from end to end of the rollers. Third, to provide an improved roller bearing in which the parts are simple and economical in structure, few in number and easily assembled. Fourth, to provide. an improved roller bearing in which the parts are so arranged that the wear and friction of the parts is reduced to a minimum.

Further objects, and objects relating to details of construction, will definitely appear from the detailed description to follow.

A structure embodying the features of our invention is clearly illustrated in the accompanying drawing, forming a part of this specification, in which,

Figure 1 is a detail longitudinal section of our improved bearing, taken on a line corresponding to line X-X of Fig. 2. Fig. 2 is an end elevation of our improved bearing with the outer cone or boxing cone removed. Fig. 3 is a detail section taken on a line corresponding to line XX of Fig. 2, showing how the rollers are retained on the cone.

In the drawing, similar reference characters refer to similar parts throughout the several views. j

Referring to the drawing, the outer or boxing cone 1 is adapted to be inserted in a suitable hub, as 7, or it is evident it may be formed integral with the wheel or pulley. The rollers 2 are conical and are formed of a uniform taper from end to, end. The outer or enlarged ends of the rollers are formed crowning or convex as at 11 so that they bear only at central points against the projecting flange 6 of the inner cone 3. At the small ends of the rollers are axially-projecting retaining pins 8, which, when the structure is assembled, project into the groove 9 of the retaining ring 5. This retaining ring is preferably sleeved upon the cone 3 which is shouldered to form an abutment therefor. The ring is preferably retained by spinning up or upsetting the end of the bearing cone as at 10. It is evident that it might be secured in numerous ways.

We have illustrated the cone 3 mounted upon the axle 4 as it is one of the objects of this invention to provide an effective roller bearing for vehicle wheels, such as automobiles, and the like. It will be understood that when adapted for this purpose, the bearings are arranged in pairs, and, on aocount of the conical features, serve as effective thrust bearings.

The groove 9 in the retaining ring 5 is of such size that, when the boxing cone 1 is in place with the parts in their normal operating relation, the retaining pins 8 of therollers do not contact with the ring, but merely serve to retain the rollers in position when the outer or boxing cone is removed. The flange 6 of the inner bearing cone 3 is inclined inwardly so that it not only serves as an effective thrust bearing for the convex or crowning end of the rollers, but oo-acts with the flange 5 in retaining the rollers, it being impossible to disengage the same therefrom without removing the flange 5 see Fig. 3. By thusarranging the arts, the necessity for cages or journals for t e rollers is obviated. The rollers are entirely free to travel about the cones and impinge with each other and with the cones throughout the entire length of the rollers. This keeps the rollers in proper position relative to each other and to the cones and distributes the load thereon. Another very great advantage is that when the outer or boxing cone is removed the roll plied, and it is evident that it will perform its function although-it'may not be a perfect fit.

It is, however, very easy to secure an accurate adjustment and fitting of the arts.

Numerous other advantages t ran those specificall mentioned will readilyappear to t ose skil ed inthe art to which this invention relates.

IN e have illustrated and described our improved bearing in detail in the form preferred by us on account of the structural sim lioityand economy and convenience with w rich it may be assembled. VVeare, however, aware that it is capable of considerable variation in structural details without departing from our invention.

Having thus described our invention,

what we claim as new and desire to secure by Letters Patent is 1.
